GIVEN
The equation of the line is given to be:

SOLUTION
The equation can be written in the slope-intercept form of a line:

This is done by making y the subject of the formula. This is shown below:

Therefore, the slope is 8/3.
Recall that for parallel lines, the two slopes are equal, and for perpendicular lines, the product of the slopes is equal to -1.
Hence, the parallel slope will be:

and the perpendicular slope can be calculated as;
